Be it known that I, ALLEN Mosrmn, a citizen of the United States ofAmerica, residing at Detroit, in the county of Wayne and State ofMichigan, have invented cer tain new and useful Improvements in Non-Glare Reflectors, of which the following is a specification, referencebeing had therein to the accompanying drawings. i j The inventionrelates to headlights for vehicles and has for its object theelimination of the glare or blinding rays, while maintaining a,suflicient-concentration of the light to stronglyilluminatethepathinfront Specification ot Letters Patent.

flector B for the concentration of the light from the lamp C arranged atthe focal point. D is a segmental reflector insertible within thereflector B, but of a conical instead of a parabolic form. The reflectorD quarter unobstructed.

covers more than one-half of the reflector B, and preferablysubstantially three-fourths of the surface thereof, leaving the lower Asillustrated in Fig. 3, the rays from the "lampC, which are reflected bythe conical of the machine. In the present state of the art parabolicreflectors are commonly used for concentrating the rays of thelamp, andthe blinding glare is due to th'ese 'concen-. trated rays. The directrays from the lamp are not obj ectionable e'ven when supplement ed byreflected rays from -the1 rear, pro-. viding that the angle ofdivergence is reflector. Heretofore, various constructions so as toobstructany raysabovethehorireflector D, are notaltered asto their di-;,verge nce and therefore are not highly conof the parabolic reflectorB, are substantially parallel and arehighly concentrated.

N one of these rays, however, will pass above the horizontalandthey,'therefore,-serve to illuminatethe road without any'blindingglare. Thus I have combined a wide an- A 'gle of"illuminationwith'a highconcentranot limited, as by the use ofqa parabolic tion of light uponthe road immediatelyin front of the machine. have been devised forshielding the lights,

bolic reflector is used, it is necessaryto ob-' struct more than halfofthe lamp area;-

re'flector might be integral.

This is obj ectionableas itis desirable to have 7 some ofthe higher raysfor the detection of obstacles ahead. With; other constructions thelight concentrated. by the reflector is dispersed by lenses or prisms atthe front, 7

but this interferes with thebestillumination of the road. With myimproved con-F struction no part. of the headlight isobstructed, but thehigh: concentration of light is limited to thoserays which are directedupon the path in front of the carand are below the central axis'offthelam'p.
